April 20, 2018

The weather has been cooperating of late, and we continue to make good progress on roundabout construction. The two big takeaways this week:

Sidewalks are getting installed for pedestrian access; this includes between Vine and Healdsburg Ave (a sidewalk route that never previously existed for the City), plus the rail trail now connects to Mill Street East. In the coming weeks, sidewalks on South Healdsburg Avenue to Singletree will also be installed.

A subcontractor will start to install the irrigation system and top soil in several areas around the roundabout to prep for greenery planting.

And now on to the rest of the roundabout construction update:

What’s Happening Now?

HAPPENING NOW:
- Sidewalks are getting installed for pedestrian access; this includes between Vine and Healdsburg Ave (a sidewalk route that never previously existed for the City), plus the rail trail now connects to Mill Street East. In the coming weeks, sidewalks on South Healdsburg Avenue to Singletree will also be installed.

- A subcontractor will start to install the irrigation system and top soil in several areas around the roundabout to prep for greenery planting.

- East Mill Street is now open to eastbound to vehicular traffic.

- Railwork installation was completed by mid-March 2018. All of the lines, tracks, ties, and other work is now laid within and outside the circle. This is a huge milestone.

LOOKING AHEAD:
- In May, a subcontractor will place lithocrete, an architectural concrete with embedded recycled materials, on South Healdsburg Avenue. This along with cobbles placed in the center circle will be used to delineate the flow and direction of Foss Creek. This decorative cobble feature is also porous, which will help cut the amount of storm water run-off.
